Draw samples from a noncentral chi-square distribution.
The noncentral distribution is a generalisation of
the
distribution.
Parameters : | df : int
nonc : float
size : int or tuple of ints

Notes
The probability density function for the noncentral Chi-square distribution is
where is the Chi-square with q degrees of freedom.
In Delhi (2007), it is noted that the noncentral chi-square is useful in bombing and coverage problems, the probability of killing the point target given by the noncentral chi-squared distribution.
